IOS

iOS is an operating system created by Apple Inc. for use in the iPhone series of smartphones. Although connecting iOS devices to Linux is not supported by Apple, the libimobiledevice project provides libraries and tools to connect and transfer data between iOS devices and Linux machines.

Usage

Preparation

In order to be able to automatically mount your iOS device (such as an iPhone) when connecting it or to enable USB tethering, you need to install libimobiledevice and to activate the usbmuxd service.

Add the following to your configuration.nix:

services.usbmuxd.enable = true;

environment.systemPackages = with pkgs; [
  libimobiledevice
  ifuse # optional, to mount using 'ifuse'
];

If you experience issues mounting or pairing your device (for example as described here), you can try to switch the usbmuxd daemon package to an alternative more updated implementation, usbmuxd2.

services.usbmuxd = {
  enable = true;
  package = pkgs.usbmuxd2;
};

Mounting

Mounting the device via iFuse is possible with the following commands

$ mkdir /tmp/iphone
$ ifuse /tmp/iphone

Tethering

Tethering on iOS is possible via Wifi hotspot, Bluetooth or USB. In order to enable USB tethering, first enable tethering in the iOS networking settings. After that run following command

$ idevicepair pair

Confirm pairing by accepting the connection on your iOS device. After that an ethernet device will appear in your network device list.

Maintenance

Factory reset

The following section describes how to perform a hard/factory reset and reinstalling the latest firmware. First install and enable the required daemon and package.

services.usbmuxd.enable = true;
environment.systemPackages = with pkgs; [
  idevicerestore
];

Shutdown your iDevice and put it into DFU/recovery mode. How to achieve this depends on your iDevice model. See DFU Mode on the iPhone Wiki for more details.

Once your iDevice is in recovery mode, run following command to reset your device. You will get asked which firmware to install and a final confirmation that everything will be erased.

Warning: The following command will reset your iPhone. All user data will be lost. Be sure to backup everything before proceeding.

# sudo idevicerestore --erase --latest
